The same letters and figures of reference are employed to denote the same parts in all the views.

a (see Figs. 1 and 2) shows a band traveling round rollers mounted in the frame I) of the machine. The band is formed of a number of metal strips 0, (see Figs. 6 to 9,) connected together by links (Z, Fig. 8. The metal strips may be covered with felt on the side which carries the card or other article to be colored. The band rests at each side on a plate 0. On the band a I fitseveral say threestout metal springsf, extending transversely of said band, each carrying in lugs g a rod h, with clips 6 to hold the card.

j shows lugs or bosses projecting from the ends of the rods It. (See Figs. 12 and 22.) As the band a travels these lugs or bosses j pass over stops or cams 70, located at the sides of the band a, Fig. 12, which are forced inwardly under the lugs or bosses j in the manner hereinafter described by the action of the operating-treadle. The effect of the lugs or bosses j passing over the cams 7c is to force them upwardly and turn the rod 7!, thus raising the clips 2', so that a card to be colored may be slipped beneath the said clips in position to be drawn onto the band a. As the band a travels along the clips 2' carry the card with it until it is in position for coloring, when the stops m are brought inwardly by the action of the operating-treadle and coming against the bar f effectually prevent any undue forward motion of the belt until such stops are withdrawn. Motion in a backward direction is prevented by springs 12, inserted in grooves 0 in the plates 6. (See Figs. 9, 12, and 13.)

The spring-pillar 3), Figs. 1 to 5, is mounted on a suitable base p, attached to the frame 7), and comprises a hollow vertical cylinder in which a plunger 9 works, r being a spiral spring pressing upwardly on the plunger q.

' This plunger q is threaded, as shown, and on the threaded portion screw two disks .9 6, (one to lock the other,) by adjusting which the travel of the plunger is regulated.

at shows the rod connecting the plunger q to the treadle or other driving mechanism of the machine.

0; is a bar projecting horizontally from the top of the plunger g. This bar 2) carries an adjustable nut or sleeve 20, from which is carried a horizontal rod in, to which are fixed or attached, preferably at right angles, two (as shown) or more other rods, y, on which latter slide sleeves or nuts 2, and through holes in these sleeves .2 the vertical stencil-holders 1 pass, being held at the required height by setscrews 2.

The method of attaching the stencil to the holders 1 is shown clearly at Fig. 2A, where 3rep resents the stencil. 1 shows foot of stencilholder, (which is hollowed and threaded,) and 4 shows screw connecting the two, the head of the screw 4 being sunk in the stencil, as shown, in order that there may be no projections on the bottom of the stencil.

For spraying the color any convenient and suitable form of spraying-nozzles may be used. The general form is illustrated in Fig. 10, which shows pipe-lines 1 1 and '15 for conduct ing the cold and heated compressed air, a valve-knob 16, handle 16, color-reservoir 16 and spray-point 16 To the spraying-nozzles, however, I apply a two way valve. (Shown in sectional view at Fig. 11.) I also use this valve in connection with hot-air jets 5, Figs. 1 and 2, which are arranged to point directly onto the stencil. A pipe 6 from these jets leads through a suitable heating agency and then connects with pipe 15, leading from the two-way valve.

Reverting to Fig. 11, 7 shows a valve mount:

ed on a valve-spindle 8, and 9 and 10 show seatings of the said valve. A spiral spring is provided at 11, adapted to keep valve 7 on its upper seat 9.

12 and 13 are guides to the valve-spindle 8, which are perforated, as at 12 and 13, Fig. 11. to allow of the passage of air.

14 is a pipe from compressed-air supply, and 15 a pipe leading in proximity to a suitable heating medium. When the valve 7 is in the position shown in the sketch, the compressed air entering at 14 is unable to pass said valve, but finds a passage downward through the pipe 15 to the heating medium through which it passes, being heated in its passage and is delivered through the hot-air jets 5 to dry the color after being applied by the spraying-nozzle. If the knob 16 is depressed, so that the valve 7 is forced down onto the seat 10, the compressed air is free to pass through the spraying-nozzles and spray the color and simultaneously close the valve to pipe 15 and to the hot-air supply at 10. This arrangement is to prevent the spray of color being diverted from its course by the jet of hot air playing on the stencil.

Instead of having spraying-nozzles operatrd by hand I may mounta number of these nozzles on a suitable frame attached to the ICC machine-frame 6 and located above the stenin a socket 18 which may be attached to the frame the socket having a set-screw 19 litted therein for holding the device at any required height. 20 shows pipe from colorsupply; 11, tap: 2-2, forked bell-crank levers pivoted at 23 for engaging with the nuts 28 and 28"on spindles 2%) and 29, operating the air and color valves, respectively, and 2% wire or gut i perating bell-crank levers 22 and actuated from the driving mechanism. 25 shows pipe from compressed-air supply, and 26 pipe passing in proximity to the heating agency for the hot-air drying-spray. The sprayingnozxles ii are titted with the twoway valve above described. Horizontal arms 27 of the levers 22 operate the air and color valves by engaging the nuts 2% and 28, and thus raising the valve-spindles 29 and 29. By setting the nut on the color-valve spindle a little higher than that on the air-supply spindle the color-vaive may be opened a little while after the air-valve is opened. (See Fig. Referring to the driving mechanism of the machine and first considering treadle-driving, to, Fig. 2. shows a treadle hinged to the back of the machine and held in position by a spring 31) or other suitable means. This treadle is shown in side view in Fig lS. Two rods 31 32 are actuated by this treadle, 32 being the rod which brings down the stencil-plate, being suitably connected to rod u, working in pillar p, see Fig. 2.) and which it is not desired to operate until the end of the stroke of the treadle. in order to effect this delay in operating the rod the foremost part of the treadle is made independent of the rest and is connected to a rod 3%, hinged at 35, which rests upon the lower bar 36 of the frame 36. which is adapted to slide upon the rod 132. \Yhen the treadle 30 has been pushed down. the top bar 37 of the frame 36 will have reached the cross-bar 3s, lixed to the rod 3; through which frame 36 is adapted to slide, and on pressing the heel on the part 33 of the treadle the bar 3% will bear upon the lower bar P6 of the frame 36, causing the top bar 37 to press on the cross-bar 38 of rod 32, and thus lower said rod. The rod 3i being simply attached in a suitable manner to the treadle 30 is operated as soon as the main part of the treadle is moved. This rod 31 is pivoted at its upper end to a link 3i, pivoted at 3-2 to a disk or cam 39, which link is adapted to engage the stud 39 on the cam 39 when the rod 31 is actuated downwardly. (See Figs. 17 and 12.) This cam is carried by a spindle to, mounted on the frame of the machine. A part of the periphery of the disk 3.) is toothed and gears with a pinion Ti on the spindle of the right-hand roller of the traveling band (1. A ratchet-and-pawl clutch i2 is provided adjacent to the pinion i1, so that this latter is inoperative on the return stroke of the rod 31.

+3 shows the cam portion of the disk 39, and 1% showsastop on the end of the cam 43.

\Vhen the rod 51 is drawn down, the link 31 engages the stud 39 and the earn *3 turns and bears upon the pin $5 on the sliding piece i6, working in the slotted bracket N, depend- 1 ing from the frame Referring to Figs. 14; and 15, it will be seen that the pin *5 is on the extremity of the bar T8, pivoted at it) to abracket50,dependingfromtheframeb. The depression of this pin *5 by the cam i3 resuits in the drawing down of fork 51, which turns the two bent levers 52 about their pivots 53 in the direction indicated by the ar rows at Fig. 14. The tops of the levers 52 form stops in, so that when the band/( has been turned, by means of the pinion ati, sufficiently to bring the card in place beneath i the stencil the cam i3 will have moved the stops m transversely into position in front of the transversely-disposed bars f, thus locking the traveling band 1/ against further movement. The stops or cams Z are operated at the same time as the stops in by means shown at Fig. 16. Each of the stops m is connected by links 80 and 81, pivoted at 5T to links 82, in turn pivoted at 5 1 to the frame 1), and carry on their ends the cams Z. As stops m move inwardly cams Z' also move inwardly and are brought in position to engage with lugs or bosses j and lift clips f, as heretofore described.

Referring to Figs. 21, 22, and 23, 55 and 56 show two standards or vertical plates between which the cards or other articles to be colored are stacked. Space is left, as shown at 55, Fig. 23, between the bottom of these plates or standards and the table on which the cards are stacked suilicient for one card to pass. 57 58 show two slots or grooves in which slide two bars 59 60, joined by a crossbar 61, by which the two bars 59 (30 are slid by hand in the slots 57 and 5S beneath the plate 55, thus pushing one card forward into the clips I. By withdrawing the cross-bar ($1 and again advancing it another card is pushed into the clips, and so on. 62 shows strip of metal to assist in keeping cards in position.

At Fig. 28 is shown a method of dispensing with a traveling band. (53 shows a plate on which the cards are stacked in the position indicated by the dotted lines at 6T. 65 shows strips against which the edges of the cards are set. These strips are shown in section at Fig. 29. In coloring cards stacked in this way the stencil is brought down onto the top card, which is colored,dried,and removed. The stencil is lowered a little farther each time correspondingly with the diminishing height of the stack of cards.

Referring to Fig. 26, (:36 shows a drivingpulley for driving by power, and (57 and 68 speed-pulleysoperativelyconnected by belting 6T. 69 shows a clutch for connecting up the pulleys 68 with the mechanism for operating the machine. The clutch 69 is thrown into i and out of gear by means of a rod 70 and bellcrank lever 71 engaging a slotted. sleeve 69, the whole being operated by hand. (See Fig. 25.) The mechanism is operated by two cams 72 73, actuating two frames 74 75, the rods leading from which take the place of and actuate the stencil, belt, and stop mechanism in the same way as the rods 31 32 in the case of treadle-driving. By disconnecting clutch 69 and attaching a rod 7 6 to a treadle treadle-driving of the cams may be substituted for powerdriving.

In operating the machine a card is fed into the left-hand clips 2', (see Fig. 12,) then, taking the case of a treadledriven machine, the treadle is depressed, carrying the card along until in position beneath the stencil, in which position it is locked in the manner previously described. The stencil is then brought down by depressing the foremost part 33 of the treadle, the color is applied, and afterward the hot-air jet to dry the stencil-card. On releasing the treadle the belt remains stationary on account of the ratchet-and-pawl clutch L2. The stops m are withdrawnand the belt released. At the same time as the stops m are withdrawn cams 70, Fig. 16, are moved from under the arms j, allowing the clips to fasten onto the card which is next to be operated upon, so that when the treadle is again depressed the belt is carried forward, the clips 2' being released from the card by reason of the lugs or bosses j engaging the cams 77, (see Fig. 12,) and thus turning the rod h. The card is delivered onto another traveling band 78 (see Figs. 1 and 2) and carried away to any suitable receptacle.

In operation a set of stencils are so cut that each stencil of the set will allow only the portions of the card which it is required to print in one particular color to be affected by the color, a different stencil of the set being employed for each different color used. A stencil is placed in position and a series of cards by the mechanism above described are successively brought beneath it and colored in one especial tone by the spraying-nozzle. A new stencil and spraying-nozzle provided with a different color are then adjusted in position and the same series of cards passed through the machine to receive their second required color, and so on until all the required colors have been properly placed on the cards.
